HT-5500 is a handheld digital tachometer with high performance and pioneering technology along with a sophisticated body. It can be operated easily as both a contact and non-contact type digital tachometer, in which various rotation measurement technologies are used.
Various measurement parameters such as rotation (r/min, r/s), accumulated rotation (count), line speed (m/min: contact and non-contact, mm/s: contact) and period (ms) can be measured. Both the analog signal output and pulse signal output are available as standard. Analog signal is used for recording the rotational data at data recorder etc. Pulse signal is used as external sampling signal at FFT analyzer for tracking analysis.
Wide measurement range with high technical functions from 6.0 r/min (low-speed rotation) to 99999 r/min (high-speed rotation) is provided.

Line speed measurement is possible by setting the diameter of rotational object even though it is non-contact measurement. (Circumferential ring such as KS-100/KS-200 should be attached at HT-5500 when it is contact measurement.)
